2 Claims.

This invention relates to collapsible golf has carriers.

It is an object of my invention to provide a novel and improvedcollapsible golf bag carrier in which the wheels as well as the grippinghandle may be collapsed into retracted position to form a compact unitfor easy transportation thereof to and from the golf course.

It is another object of my invention to provide a golf bag carrierhaving an upstanding member with a pair of wheels respectively mountedon the outer portions of two pairs of toggle arms, the inner ends ofsaid toggle arms being mounted on said upstanding member with provisionfor shifting movement longitudinally thereof to permit positioning saidwheels in outwardly extending diametrically opposed operative positionas well as permitting the retraction of said wheels inwardly andupwardly into substantial engagement with the upstanding member to liesubstantially flush therewith.

It is a further object to provide a golf bag carrier having an elongatedupstanding member with two pairs of toggle arms operable in a singleplane disposed through said upstanding member, said toggle arms beingrespectively interconnected at their outer ends by a pair of linkspivoted thereto and each having a wheel mounted thereon, said wheelsbeing disposed in substantially parallel relation throughout theoperation of said toggle arms to retract or project said wheels.

More specifically, it is an object to provide a golf bag carrier havingan elongated upstanding member adapted to have a golf bag attachedthereto and provided with a retractable wheel mechanism including twopairs of substantially coplanar toggle arms with the inner ends of theupper arms being shiftably mounted on said member and the outer ends ofeach pair of arms be ing pivotally interconnected by a link having awheel journaled thereon to maintain said wheels in substantiallyparallel planes during retraction and projection thereof, said togglemechanism having two pairs of opposed arm-engaging cradles adapted toreceive the respective inner portions of said arms when in fullyoutwardly projected position to permit said arms to be securely lockedin said position, certain of said cradles being fixed to said upstandingmember to positively lock said toggle Wheel-supporting mechanism againstrotation. when in operative position.

It is still another object to provide a collapsible goli' bag carrierhaving a rearwardly extending stabilizing foot member adapted tocooperate with said wheels when in projected operative position tosupport the carrier unit when the wheels are projected outwardly whensaid unit is in stationary position. i

These and other objects and advantages of my invention will more fullyappear from the following description made in connection with theaccompanying drawings wherein like reference characters refer to similarparts throughout the several views and in which:

Fig. 1 is a front elevational view of my improved golf bag carrier withthe wheels shown in retracted position by dotted lines and having a golfbag mounted thereon;

Fig. 2 is a vertical sectional view taken substantially along the line2-2 of Fig. 1 showing most of the structure shown in Fig. 1 in sideelevation.

Fig. 3 is a fragmentary vertical sectional view taken substantiallyalong the line 3-3 of Fig. 2; Fig. 4 is a central vertical sectionalview taken substantially along the line 4-4 of Fig. l; and

Fig. 5 is a fragmentary sectional view taken substantially along theline 5-5 of Fig. 4.

As shown in the accompanying drawings, I provide a novel and extremelysimple golf bag carrier having an upstanding main frame member such asthe tubular element 8 having a handle 9 normally disposed in forwardlyextending relation thereto and pivotally connected to a suitable elbowmember H) which is fixed to the upper extremity of upstanding tubularmember B. Any suitable meansfor retaining the handle member 9 inoutstanding position may be provided, such as the shiftable sleeve llslidably mounted thereon and having a spring [2 for urging the sleeveinto locking position. Said sleeve H surrounds a portion of the handlemember 5 as well as an outstanding portion of the elbow in to lock saidhandle in forwardly extending position.

A rearwardly extending foot member I3 is mounted at the bottom extremityof the upstande ing member 8 to stabilize the structure while instationary position,v as will be brought out hereafter. Suitableattachment means are provided such as the lower attachmnet meanscomprising a bag bottom receiving cradle I4 fixed to the stabilizingfoot l3 and having a pair of spaced upstanding arms thereon with a strapI5 for surrounding the lower portion of the bag and an upper attachmentmeans comprising a curved bracket I6 fixed to the upper portion of theupstanding member 8 and having an attachment strap I! connected theretofor securing the upper portion of the beg to said upstanding member 8.

A fixed mounting member I8 is secured to the lower portion of tubularmember 8 and has a pair of outstanding arm-receiving cradles l9 fixedthereto. A shiftable sleeve 20 is slidably mounted on tubular member 8above the fixed mounting member l8 and has a pair of outstandinginverted arm-receiving cradles 2|. A pair of lower wheel sup-portingarms 22 and 23 are respectively mountedtinthecradles J9 asnby'the fixed.pivot pins 24tthrough the inner portions .of the arms and cradles. Apair of upper wheel supporting arms 25 and 26 are pivotally connected atthe inner ends with the inner portions of the respective cradles 2| forshifting movement-"therewith. A pair of interconnection links21aare.respectively connected to the outer ends of the upper and lowerarms at the respective sides #o'fthe carrier, as by the four pivot pins28. Thewheels 29 are journaled on suitable shafts mounted oninterconnection ,links 21, and as best shown in Fig.3, aipairo'f i'stopbars3ll are'interposed between the. outer marginal portions :of the armsto prevent jackk'nifing' "of the wheels "during the projectionand.retraction thereof,

From the foregoin'gparagraph describing the wheel supporting mechanism,itwill' be seenthat thepivoted arms2'2 and'25,and 23 and 25 form two.pairs of toggle arms' which are'mounted on the upstandingtubular'memberB to permit the projection and retraotiorr'of thewheels29. The two .pairs of toggle :a'rmsexten'd outwardly'on opposite sidesof :the upstanding "member '8 "and lie 'in "a' single planesubstantially through said upstanding member 8 throughout "theirentireoperation. Thedouble pivotal connections of the links .21 permit thewheels 29 tobe maintained substantially parallel to each other and atright angles to the plane through said toggle armsand insubstantiallyparallel relation to the upstanding member 8. Thei'toggle"arms hold said links 21 in positively fixed "substantially parallel'relation to the upstanding member 8 when said wheels are in extremeoutwardly and downwardly projected position. 'A'sprin'g "clip 3| is-'fixed-at one "end toith'e:shiftablecradles2 I and is adapted to engage"theffixe'd cradles f'l9; to securely lock said wheels; in 'operative"position with ""the lo'wer arms "22. and 23 positively engaged incradles l9, and the upperarms 25*and 26 positively engaged in cradles2|. 7

'The operation of my improved golf'bag carrier is obviousfromthedrawing's. With the carrier folded upv into "retracted position asshown inthe dotted .lline position inFig. 1 and the fullline carry, unit.is "formed. The whee1s"2-9 lie in adjacent side'by side -"relation tothe *golf bag and the elongated frame "member 8, and the wheels-.outwardly into fully extended operative position. 7

It will be seen that .I "have provided an extremely simpleand-compactlycollapsible golf bag carrier having a togglewheel/supporting mechanism with the arms thereof lying in a singleplanesubstantially through the upstanding frame member 8 and with the wheels29 allel relation between the wheels in the extreme retracted position,the wheels lie flat against the side of the bag and the upstanding framemember 8; and when the wheels are in downwardly projected operativeposition, they are locked'in outstanding position laterally of theupstanding frame member 8. The inter-connector links 21 permit saidwheels 29 to be maintained at right anglesto the plane ofsaidstogglermechanism and substantially parallel to the upstanding framemember 8. It should be noted that the axes of rotation of the wheels arecoincident in operathereof=constantly..maintained inpa'rallelrelation-and disposed at. right anglesto the plane of said togglemechanism. By maintaining the partive position and in extreme retractedposition and also remain substantially coincident during retractionandprojection thereof.

It will, of course, be understood that various changesmay'be made in theform, details, arrangement and proportions of the parts withoutdeparting from the scope of my invention.
